Service Interval: Before each use or daily

CAUTION

If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury.

Do not tamper with the interlock switches.

Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.

Understanding the Safety Interlock System

The safety interlock system is designed to prevent the mower blades from rotating unless:

1.Use wrench here for blade installation. This nut has been torqued to 130-160 ft-lb (176–217 N-m)

2.Torque to 50-60 ft-lb (68-81 N-m) Apply lubricant to threads as needed to prevent seizing. Copper-based anti-seize preferable. Grease acceptable substitute.

• The right side motion control lever is moved to

the center, operating position.

• The blade control switch (PTO) is pulled on.

The safety interlock system is designed to stop

the mower blades if you move or release the right

side motion control lever into the PTO disengage

position.

C.Apply lubricant to threads of blade bolt as needed to prevent seizing. Copper-based anti-seize preferable. Grease acceptable substitute. Install blade bolt finger tight. Place wrench on the top spindle nut then torque the blade bolts to 50-60 ft-lb (68-81 N-m).

• The right side motion control lever is moved to

the center, operating position, the parking brake

is engaged, and the blade control switch (PTO) is

pulled on.

Checking the Safety Interlock System

1.Start the engine.

2.Set the parking brake.

3.Move the motion control levers forward.

The engine should initiate shutdown after momentary pause.

4.Start the engine and release the parking brake.
